FORMER Docker Tendai Mzungu has been elevated to Greater Western Sydney's senior list to fill the opening created when ruckman Tom Downie was placed on the long-term injury list.

After playing 102 games at Fremantle from 2011-16, Mzungu joined GWS in last year's rookie draft at pick No.15 overall.

The 31-year-old midfielder is now firmly in contention to make his club debut for the Giants in their round one clash against Adelaide at Adelaide Oval on Sunday, March 26.

GWS revealed on Thursday Downie had occasionally spent time away from the club in recent months because of mental health issues, with the decision to move him to the long-term injury list made to allow him to focus on getting the support he needs.

With GWS vice-captain Stephen Coniglio (ankle), Brett Deledio (calf) and Matt de Boer (hamstring) all set to miss games early in the season, and youngster Jacob Hopper (back) having played just a half of footy in the reserves last week, Mzungu's experience and versatility could play in his favour when Leon Cameron picks his best 22 to face the Crows.

Mzungu gathered 22 possessions and kicked a goal in his only appearance of the JLT Community Series against West Coast.
